American and Alaska strike deal around Seattle flights

American Airlines and Alaska Airlines are deepening their ties in Seattle, where both carriers compete against Delta Air Lines

DALLAS -- American Airlines and Alaska Airlines say they will cooperate more closely on West Coast service, including new American flights from Seattle to India's technology hub in Bangalore.

Instead, they announced Thursday that they will expand revenue-sharing to cover international flights in Seattle and Los Angeles.

American initially said U.S. Transportation Department approval was needed but later said that was not the case. The department did not immediately respond to a request for comment.

American said it will begin flying to Bangalore in October. No U.S. airline currently flies to Bangalore.

American said it will also launch Seattle-London service next year, and could add other international destinations from Seattle.

Alaska will become a full-fledged member of oneworld, one of the three global alliances that dominate the industry. American is already a member.

Alaska hopes a closer tie-up with American will help it grow and start filling a gap in its service. The airline flies to Canada and Mexico from its hometown of Seattle, but it faces growing competition from Delta Air Lines, which has built an international gateway there with flights to Europe and Asia.

American, which is based in Fort Worth, Texas, has tried and failed before at flying to India. In 2012, when American was going through a bankruptcy reorganization, it dropped flights between Chicago and Delhi.

“The Indian market is much, much more mature than it was then,” said Vasu Raja, the airline’s senior vice president of network strategy. “There are so many U.S. companies with such big bases of operations in India, and Bangalore is one of the highest-growing business markets for our corporate customer base.”
